Yes, this is due to the scientific superiority of the USSR, it was called "Project Super-Fishbed". Foolish Americans, they'll never reach the Soviet level of technological progress.Once the pilot is fully seated and the MIG-21 is powered up, the pilot in immediately endowed with Iron Man like capabilities. The pilot does not need radar. His vision is enhanced not just throughout the EM spectrum, but also in resolution, enabling him to literally see the F-22 beyond any radar capabilities. Trust me on this one. We got a MIG-21 in Area 52 and still have not figured it out despite decades of studying it.
